Thanks Yaroslav for the invitation and greetings to everyone. I used to participate on the anthrogenica boards, but discussion there died a while ago about z1828. Since then I've been following this thread too, but I'm no expert of course on the theme. Hopefully the data could be of any sort of help in the research, we'll see.
So as you already know, my haplogroup is zs3128. Pecoraro Velardi and Correira were my closests relatives according to ftdna on 12str which is not quite a recent relation.
My farthest known ancestor is Mathias R. 1682-1764, probably arriving from Pfalz-Neuburg. The family name can be traced back to the 15th century, probably originating at the northern edge of the high alps, Bern, Luzern area. Earliest mention is 1433 Baden, Switzerland.
